Amazing Soap

This is by far the best soap my boys have tried. My boys have eczema and refuses to shower, no matter what soap we use, they didn't like it. Since using this, taking shower is not a problem anymore. It leaves their skin soft and moisturised.

You can feel this soap going to work against the itchy, oozy yuck that is eczema. It's greatly helped to decrease my flair ups as they happen. I highly recommend this product.

This soap is a fave now. I use it daily. It rinses off easily. I like the way the grit in it exfoliates & leaves my skin feeling soft.
